The inner Neal One end of each of the channels 9 and la is cylindrical container is rotated while the machine attached brackets H and respectively. ich

is in its tipped position. This permits the wet laundry to drop out of the end of the inner container into a receptacle positioned to receive the laundry. If desired, before the end doors are 2 opened, the inner container may be rotated rapidly so as to express the water from the laundry due to centrifugal force, thus causing the laundry to be semi-dried before it is ejected from serve as a hinge or pivot upon which the washing machine may be tipped. A hinge pin l3 extends through the brackets II and I2 and through the pair of channels 8 to constitute the hinge.

At the opposite end of the washing machine is' a jack l4 operated,- preferably, by hydraulic means. The Jack H is pivotally attached at ,[5 to a bracket IG fastened to the floor upon which the machine rests. The upper end of the jack I4 is pivoted at I] to a bracket l8 which nects with a support l9 fast'eiie'rl By this arrangement, the jack I4; when itis' gized, elevates one end of the washingniachine While the opposite end pivots to the hinge pm l3. This results in a tipping action of the entire washing machine. n For the purpose of introducin'gjyat to the cylinder I, a conduit 2|] extending, through plate 3 is employed.
